Mercedes-Benz E400 vs BMW 440I

What's the difference?

It is hard to immediately think of a country more suited to the convertible life than Australia. Even our coldest states (you know who you are…) are blessed with more warming sun than almost anywhere else on the civilised parts of the planet, so you’d think we’d be swanning about in dropped-top bliss almost year round.

But it’s actually in the UK (despite being cold, grey and almost always underwater) that convertibles really fly out of dealerships, with sun-starved Brits buying more than anyone else in the world. Weird, right?

Still, here they remain something of an oddity, sold in small numbers to drop-top diehards. At least partly because the convertibles of old were almost always slightly worse than their hardtop equivalents. 

But Mercedes - which makes more convertibles than most - claims to have mastered the soft-top formula with the E400 4Matic, a car it says offers all the perks of open-air motoring without any of the dynamic or practical downsides. 

Life comes at you fast, especially in the automotive industry, where model lifecycles are becoming shorter as each new generation comes and goes.

Take the BMW 4 Series for instance. It’s been a segment stalwart since 2013, but the current model’s time in the sun is finally coming to an end a little later this year.

And that got us thinking whether or not the old saying rings true in this context. So, we put the flagship 440i coupe to test to find out if the older you get, the wiser you are.
